 Technical Specifications 

1. The water-ring suction pump can instantly generate a high suction flow rate compliant with dental application standards without any waiting time; maximum vacuum: –50 kPa;
   
2. Two high-flow vacuum pumps operate in parallel; they can be started simultaneously in time-sharing mode or operate independently as backup units, providing maximum reliability for outpatient dental care.
   
3. Features an integrated modular wet suction system with an external independent water–gas separator, enabling continuous active discharge of wastewater;
   
4. The suction pump is equipped with a stainless steel pump body, stainless steel impeller, and stainless steel base, which effectively extends the pump's service life;
   
5. An intelligent microcomputer control system allows independent control of the operating status of each vacuum pump, incorporates multiple circuit protection functions, and includes an automatic delayed shutdown feature;
   
6. An external mechanical negative pressure balancing valve ensures that the negative pressure remains within the optimal range of –11 to –15 kPa, preventing damage to the patient's oral mucosa caused by excessive negative pressure;
   
7. One-touch emergency startup function: in the event of a microcomputer system failure, the device can be activated via a single button press to enter emergency mode, allowing it to continue operating while awaiting repair or rescue services;
   
8. The solenoid valve and check valve work in conjunction to ensure a stable supply of tap water;
   
9. Water intake filtration treatment protects the vacuum pump from damage during normal operation;
   
10. Equipped with a proprietary water circulation system that can reduce tap water consumption by up to 40%;
    
11. The mechanical negative pressure balancing valve provides sufficient fresh air for internal cooling and heat dissipation of the suction pump;
    
12. Water supply pressure: 200 kPa to 400 kPa;
    
13. Water consumption: as low as 2 L/min;
    
14. Noise level: ≤75 dB(A);
    
15. Dimensions (Height × Width × Length): ≤77 × 58 × 45 cm (vertical main unit) or 72 × 61 × 12 cm (external separator);
    
16. Net weight: ≤100 kg

1. Q: How many dental chairs can this suction unit support?
   A: It is suitable for 10–15 sets of dental comprehensive treatment units, ideal for medium and large dental clinics.
   
2. Q: What is the maximum vacuum and working negative pressure of this machine?
   A: Max vacuum reaches -50kPa. External mechanical pressure valve keeps stable working negative pressure at -11~-15kPa to avoid hurting oral mucosa.
   
3. Q: Does this vacuum pump have backup function for continuous clinic operation?
   A: Yes. Two high-flow vacuum pumps work in parallel. They can run simultaneously or independently as backup, with one-touch emergency start for system failure.
   
4. Q: What’s the noise level and water consumption of this dental suction machine?
   A: Noise ≤75dB(A). Adopts proprietary water circulation system, cuts tap water consumption up to 40%, minimum water consumption 2L/min.
   
5. Q: What material is the pump body made of? Any protection features?
   A: Stainless steel pump body, impeller and base for long service life. Equipped with water intake filtration, multi-circuit protection and automatic delayed shutdown.
   
6. Q: What’s included in the standard package?
   A: 1 set vacuum pump, 1 water-gas separator, vacuum tubes and drain pipe. Customized cables or pipe lengths are available upon request.
